Leaked AMD Slides Provide Glimpse of Radeon HD 7900 Features

The key features of AMD's upcoming Radeon HD 7900 family of graphics cards have leaked out ahead of a rumoured 22nd December launch.

The 'Southern Islands' GPU family powers the cards, but AMD is keeping the design close to its chest - despite recent leaks offering a glimpse of the reference design's overall layout and hints of a 384-bit memory bus offering 1.5GB of GDDR5 dedicated graphics memory.

Now, a fresh leak from DonanimHaber adds a few more details to the mix, including confirmation that the 7900 family will be based on a 28nm process size with a 'revolutionary architecture.'

According to the slides, the boards will be based on the PCI-Express Gen3 specification, and include AMD's PowerTune and ZeroCore power management technologies to ensure smooth running both under load and at idle.

Additionally, AMD's Eyefinity 2.0 will include Dolby Digital Master (DDM) audio support, a 5x1 landscape layout mode, AMD's HD3D technology, new bezel compensation functionality and the ability to run at custom resolutions.

Finally, AMD is pushing its App Acceleration feature, which allows software to offload processing onto the GPU - including AMD Steady Video 2.0, improved UVD, and new software partnerships to ensure wider support in the third-party development ecosystem.

AMD, for its part, is refusing to confirm the accuracy of the slides, which were reportedly provided to partners under a non-disclosure agreement (NDA).
